Secularism is the principle of the separation of government institutions and persons mandated to represent the state from religious institutions and religious dignitaries. One manifestation of secularism is asserting the right to be free from religious rule and teachings, or, in a state declared to be neutral on matters of belief, from the imposition by government of religion or religious practices upon its people.[Notes 1] Another manifestation of secularism is the view that public activities and decisions, especially political ones, should be uninfluenced by religious beliefs and/or practices.[1][Notes 2]

The purposes and arguments in support of secularism vary widely. In European laicism, it has been argued that secularism is a movement toward modernization, and away from traditional religious values (also known as secularization). This type of secularism, on a social or philosophical level, has often occurred while maintaining an official state church or other state support of religion. In the United States, some argue that state secularism has served to a greater extent to protect religion and the religious from governmental interference, while secularism on a social level is less prevalent.[2][3] Within countries as well, differing political movements support secularism for varying reasons.[4]

Holyoake invented the term "secularism" to describe his views of promoting a social order separate from religion, without actively dismissing or criticizing religious belief. An agnostic himself, Holyoake argued that "Secularism is not an argument against Christianity, it is one independent of it. It does not question the pretensions of Christianity; it advances others. Secularism does not say there is no light or guidance elsewhere, but maintains that there is light and guidance in secular truth, whose conditions and sanctions exist independently, and act forever. Secular knowledge is manifestly that kind of knowledge which is founded in this life, which relates to the conduct of this life, conduces to the welfare of this life, and is capable of being tested by the experience of this life."[6]

Barry Kosmin of the Institute for the Study of Secularism in Society and Culture breaks modern secularism into two types: hard and soft secularism. According to Kosmin, "the hard secularist considers religious propositions to be epistemologically illegitimate, warranted by neither reason nor experience." However, in the view of soft secularism, "the attainment of absolute truth was impossible and therefore skepticism and tolerance should be the principle and overriding values in the discussion of science and religion."[7]

In political terms, secularism is a movement towards the separation of religion and government (often termed the separation of church and state). This can refer to reducing ties between a government and a state religion, replacing laws based on scripture (such as Halakha and Sharia law) with civil laws, and eliminating discrimination on the basis of religion. This is said to add to democracy by protecting the rights of religious minorities.[8]

Other scholars, such as Jacques Berlinerblau of the Program for Jewish Civilization at Georgetown University, have argued separation of church and state is but one possible strategy to be deployed by secular governments. What all secular governments, from the democratic to the authoritarian, share is a concern about relations between church and state. Each secular government may find its own unique policy prescriptions for dealing with that concern (separation being but one of those possible policies. French models in which the state carefully monitors and regulates the church being another) [9]

Maharaja Ranjeet Singh of the Sikh empire of the first half 19th century successfully established a secular rule in the Punjab. This secular rule allowed members of all races and religions to be respected and to participate without discrimination in Ranjeet Singh darbar and he had Sikh, a Muslim and a Hindu representatives heading the darbar.[10] Ranjit Singh also extensively funded education, religion, and arts of various different religions and languages.[11]

Some Christian fundamentalists (notably in the United States) oppose secularism, often claiming that there is a "radical secularist" ideology being adopted in current days and see secularism as a threat to "Christian rights"[16] and national security.[17] The most significant forces of religious fundamentalism in the contemporary world are Fundamentalist Christianity and Fundamentalist Islam. At the same time, one significant stream of secularism has come from religious minorities who see governmental and political secularism as integral to preserving equal rights.[18]

In studies of religion, modern democracies are generally recognized as secular. This is due to the near-complete freedom of religion (beliefs on religion generally are not subject to legal or social sanctions), and the lack of authority of religious leaders over political decisions. Nevertheless, religious beliefs are widely considered by most to be a relevant part of the political discourse in many of these countries (most notably, in western society the United States ).This contrasts with other Western countries such as Britain and France where religious references are generally considered out-of-place in mainstream politics.

The aspirations of a secular society could characterize a secular society as one which:

Refuses to commit itself as a whole to any one view of the nature of the universe and the role of man in it.

Is not homogeneous, but is pluralistic.

Is very tolerant. It widens the sphere of private decision-making.

While every society must have some common aims, which implies there must be agreed on methods of problem-solving, and a common framework of law; in a secular society these are as limited as possible.

Problem solving is approached rationally, through examination of the facts. While the secular society does not set any overall aim, it helps its members realize their aims.

Is a society without any official images. Nor is there a common ideal type of behavior with universal application.

Positive Ideals behind the secular society:

Deep respect for individuals and the small groups of which they are a part.

George Holyoake's 1896 publication English Secularism describes secularism as follows:

Secularism is a code of duty pertaining to this life, founded on considerations purely human, and intended mainly for those who find theology indefinite or inadequate, unreliable or unbelievable. Its essential principles are three: (1) The improvement of this life by material means. (2) That science is the available Providence of man. (3) That it is good to do good. Whether there be other good or not, the good of the present life is good, and it is good to seek that good.[24]

Holyoake held that secularism and secular ethics should take no interest at all in religious questions (as they were irrelevant), and was thus to be distinguished from strong freethought and atheism. In this he disagreed with Charles Bradlaugh, and the disagreement split the secularist movement between those who argued that anti-religious movements and activism was not necessary or desirable and those who argued that it was.

Contemporary ethical debate in the West is often described as "secular." The work of well known moral philosophers such as Derek Parfit and Peter Singer, and even the whole field of contemporary bioethics, have been described as explicitly secular or non-religious.[25][26][27][28]

It has been argued that the concept of secularism has frequently been misinterpreted.[29] In a 2012 Huffington Post article titled Secularism Is Not Atheism, Jacques Berlinerblau, Director of the Program for Jewish Civilization at the Edmund A. Walsh School of Foreign Service at Georgetown University, wrote that "Secularism must be the most misunderstood and mangled ism in the American political lexicon. Commentators on the right and the left routinely equate it with Stalinism, Nazism and Socialism, among other dreaded isms. In the United States, of late, another false equation has emerged. That would be the groundless association of secularism with atheism. The religious right has profitably promulgated this misconception at least since the 1970s."[29]

Another secularist organization is the Secular Coalition for America. The Secular Coalition for America lobbies and advocates for separation of church and state as well as the acceptance and inclusion of Secular Americans in American life and public policy. While Secular Coalition for America is linked to many secular humanistic organizations and many secular humanists support it, as with the Secular Society, some non-humanists support it.

Local organizations work to raise the profile of secularism in their communities and tend to include secularists, freethinkers, atheists, agnostics, and humanists under their organizational umbrella.

Student organizations, such as the Toronto Secular Alliance, try to popularize nontheism and secularism on campus. The Secular Student Alliance is an educational nonprofit that organizes and aids such high school and college secular student groups.

In Turkey, the most prominent and active secularist organization is Atatürk Thought Association (ADD), which is credited for organizing the Republic Protests – demonstrations in the four largest cities in Turkey in 2007, where over 2 million people, mostly women, defended their concern in and support of secularist principles introduced by Mustafa Kemal Atatürk.
